OKLAHOMA CITY — With a lot mileage used Sunday on Texas starting pitcher Blaire Luna, it was asking a lot to beat Tennessee on successive nights.

But there were signs of wear as the Longhorns dropped a season-ending 2-1 decision to the Volunteers.

A bases-loaded walk to freshman pinch hitter Lexi Overstreet in the sixth inning proved to be the difference, enabling the seventh-seeded Vols (52-10) to advance to the best-of-3 title series at the Women's College World Series. The fourth-seeded Horns (51-10) finished with the second-best victory total in program history, trailing only the last UT team to make it to the WCWS in 2006.

“It's tough to be done with our season a little bit earlier than what we would have liked,” Longhorns coach Connie Clark said. “But I'm very proud of this group. I thought they had an exceptional year.”

Earlier in the day, the Longhorns remained alive in the elimination bracket after a 3-0 win over Florida. Luna went the whole way and threw 141 pitches. In the evening game, another complete-game effort, she tossed 147.

“I think I could have gone a little bit longer,” Luna said. “The only thing that was really bothering me was my forearm. (It) was just kind of tightening up and there was a little blood blister on my finger.”

The bases-loaded walk to Overstreet was one of eight walks Luna gave up against the Vols. Against the Gators earlier in the day, she issued five.

Tennessee jumped ahead early on an opposite-field homer by left-handed batter Lauren Gibson, her 19th of the season. Gibson's first career homer as a freshman came against Luna.

In each of the first three innings, the Horns got a runner into scoring position, but they couldn't get a clutch hit off Vols starter Ivy Renfroe. Tory Schmidt advanced to third on a wild pitch with one out in the second, but was left stranded.

“Obviously, you want to get the timely hitting, and we didn't necessarily get it in the early innings tonight,” Clark said. “But I think that the confidence, the approach and the discussion in the dugout stayed very positive.”

Lindsey Stephens provided the only run for the Horns in the seventh with a solo homer to center.
